determine the required flash output.
5. High-Speed Sync (HSS)
Swipe up from the bottom
of the screen and tap the
sync icon to display < >.
6. Second-Curtain Sync
With a slow shutter speed, you can create a trail of light following the
subject. The flash fires right before the shutter closes.
* If the shutter speed is at or below the camera’s maximum
flash sync speed, the < > icon will not appear in the
viewfinder.
* The higher the shutter speed in HSS, the smaller the
effective flash range.
* Stroboscopic (Multi) flash cannot be used in HSS mode.
* After 100 consecutive HSS flashes, the flash’s thermal
protection may activate.
* To return to normal flash, tap the sync icon again;
the < > icon will disappear.
Using High-Speed Sync allows flash to fire at any shutter
speed. This is especially useful for fill-flash in aperture-
priority portraits.

* To avoid overheating and deterioration of the flash head, do not
use the stroboscopic flash more than 10 times in succession. After
10 times, allow the camera flash to rest for at least 15 minutes. If
you try to use the stroboscopic flash more than 10 times in
succession, the flash may stop flashing automatically. This is to
protect the flash head. Should this happen, please allow the
camera to rest for 15 minutes.
* Stroboscopic flash is most effective with a highly reflective subject
against a dark background.
* It is recommended to use a tripod and a remote control.
* A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash
mode.
* Stroboscopic flashes can be used with the “buLb” function.

The term stroboscopic flash relates to a rapid series of flashes being
fired. It can be used to capture multiple images of a moving subject
in a single photograph.
You can set the firing frequency (number of flashes per sec. expressed
as Hz), the number of flashes, and the flash output.
Calculating the Shutter Speed:
During a stroboscopic flash, the shutter remains open until the firing
stops. Use the formula below to calculate the shutter speed and set
it with the camera.
Number of Flashes / Flash Frequency = Shutter Speed
For example, if the number of flashes is 10 and the firing frequency
is 5 Hz, the shutter speed should be at least 2 seconds.
* If the flash count is displayed as --, the flash will fire continuously
until the shutter release or the battery is exhausted. The number
of flashes will be limited as shown in the table below.
Wireless Flash Shooting: Wireless (2.4G) Transmission
* This mode is not available in full-auto or program auto zones; set
the camera to P/Tv/Av/M/B (Creative Zone modes).
* A Z3R-C mounted on the camera acts as the Master; a wirelessly

3. Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will
bounce off the surface before illuminating the subject. This can
soften shadows behind the subject for a more natural-looking
shot. This is commonly known as a 'bounce flash'.
Position the flash head to set the bounce direction.
* If the wall or ceiling is too far away, the bounced flash might
be too weak and result in underexposure
* The wall or ceiling should be a plain, white color for high
reflectance. If the bounce surface isn't white it will result in
"off color" photos.

7. Modeling Flash
If your camera has a depth-of-field preview button, pressing it
activates a 1-second continuous flash, known as modeling flash.
This feature helps you observe the effect of the light and shadow
on your subject and evaluate the illumination balance, whether
you're using wireless or standard flash
* Avoid triggering the modeling flash more than 10 times in quick
succession. If you've performed 10 consecutive modeling flashes,
please allow the flash to cool down for at least 10 minutes to
prevent overheating or damage to the flash head.
* EOS 300 and B-series cameras do not support modeling flash.

5. ZOOM: Set the flash coverage
The flash coverage can be set automatically or manually. It can be
set to match the lens focal length from 28mm to 105mm. In auto
zoom, the focal length changes with the camera's zoom lens to
provide the best flash effect.
* If you set the flash coverage manually, make sure it covers the lens
focal length so that the picture will not have a dark periphery.

Number of flashes that will activate over-temperature protection:
1. Over-Temperature Protection
① To prevent the flash head from deteriorating and overheating, it
is recommended not to fire more than 100 continuous flashes in
fast succession at 1/1 full power. After 100 continuous flashes,
pause the use of the flash for at least 10 minutes.
② If you fire more than 100 continuous flashes and then fire more
flashes in short intervals, the inner over-temperature protection
function may be activated. The recycling time will be longer
(over 10s). If this occurs, the use of the device should be paused
for at least 10 minutes for the flash unit to operate as normal.

Troubleshooting
Firmware upgrade
If you experience a problem with the device, please refer to this
Troubleshooting Guide.
1. The Camera Flash does not fire
2. Auto power off

activated if the flash is set as Transmitter (Master).
→Press the shutter button halfway or press any flash button to wake
up.
② After 60 minutes (or 30 minutes) of idle operation, the flash unit
will enter sleep mode if it is set as Receiver (Slave).
→Press any flash button to wake up.
3. Auto zoom does not work.
The camera flash is not attached securely to the camera.
→Attach the camera flash's mounting base to the camera.
4. The flash exposure is underexposed or overexposed.
① There was a highly reflective object (e.g. glass window) in the
picture.
→Use FE lock (FEL).
② You used high-speed sync.
→With high-speed sync, the effective flash range will be shorter.
Make sure the subject is within the effective flash range
displayed.
③ Use Manual Flash mode.
→Set the flash mode to E-TTL or modify the flash output.
5. Photos have dark corners or only parts of the target
subject are illuminated.
The focal length of lens exceeds the flash coverage.
→Check the focal length that has been set. This flash unit has the
flash coverage between 28 and 105mm, which fits medium-
format cameras.
